Answer 2

Answer:

11 : 4

Step-by-step explanation:

Let the present age of A = 4 x and B = x

Given that,

A * B = 196

then,

4 x * x = 196

4 x^2 = 196

x^2 = 49

x = 7

A = 4 x = 4 *7 = 28

B = x = 7

After 5 year ,

A = 28 + 5 = 33

B = 7 +5 = 12

Ratio of A & B after 5 year = 33 : 12 = 11 : 4
